This example demonstrates a simple D3.js visualization that displays a centered greeting message, “Hello VizHub!”, within a web page. The code uses the `select` function from the D3 v6 library to target a specific HTML element by its ID and set its text content. The page’s styling is handled with CSS via the `styles.css` file, applying a large font size and text alignment. The message text is defined in a separate ES6 module, `myMessage.js`, showcasing modular code organization within the VizHub framework.
